Wall-mounted type air purifier based on thermal regeneration and purification method thereof

Abstract

The invention belongs to the field of indoor air purification and relates to a wall-mounted type air purifier based on thermal regeneration and a purification method thereof. The purifier comprises a sealed cabin, a draught fan, an air channel body which is composed of a plurality of air valves, a low efficient filter, efficient reproducible volatile organic compounds (VOCs) absorption module, a formaldehyde absorption module, a heating wire, a VOCs sensor, a temperature sensor, and a programmable logic controller; the sealed cabin of the air purifier comprises an air purification chamber and a heating regeneration chamber; the low efficient filter, the efficient reproducible VOCs absorption module, the formaldehyde absorption module, the draught fan and the VOCs sensor are installed in the air purification chamber of the sealed cabin from bottom to top; the heating wire and the temperature sensor are installed in the heating regeneration chamber from top to bottom; the programmable logic controller is connected with the draught fan, the temperature sensor, the VOCs sensor and circuits of the multiple air valves. The purification method comprises four modes of purifying, thermal regenerating, pollution discharging and fresh air, and further comprises two functions of indoor purification and mechanical ventilation. According to the wall-mounted type air purifier based on thermal regeneration and the purification method thereof, indoor VOCs and indoor formaldehyde can be purified quickly, continuously and effectively, and the service life of the wall-mounted type air purifier is prolonged.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, in particular to a structural design of a wall-mounted air cleaner based on thermal regeneration. Background technique [0002] With the rapid development of urbanization in our country, the number of new buildings is huge every year, and more and more new decoration materials and chemical products are used in interior decoration. These new interior decoration materials often release a large amount of pollutants such as volatile organic compounds (VOCs) and formaldehyde, causing serious indoor pollution. According to statistics, after decoration, most of the formaldehyde and VOCs content in newly built houses exceeds the standard. [0003] Volatile organic compounds (VOCs) and formaldehyde significantly affect people's comfort, health and work efficiency. Volatile organic compounds cause sensory stimulation to the human body, make the human body feel dry, irritate the eye mucous...

AI Technical Summary

Problems solved by technology

However, due to the limited adsorption capacity of adsorption materials, the life cycle of adsorption air purifiers currently on the market is short, and the adsorption materials need to be replaced frequently, otherwise the purification effect will be seriously affected

This makes it difficult for adsorption purifiers to be used for a longer period of time
